Description

The invention relates to the textile industry and can be used on two final ribbon machines for cotton and similar machines.

The purpose of the invention is to facilitate the operation,

FIG. 1 and 2 are a diagram of the device with different positions of the pusher; in fig. 3 and 4 - section A-A in FIG. 1 (work of the internal direction with a knot for filled cans); in fig. 5 - the location of the basins in the known device; in fig. 6 - the proposed device; in fig. 7 - main pusher positions.

The device for changing the cans of a two-outlet belt machine contains a drive 1 with a stem 2 and a pusher 3, a pull 4 with a catch 5, guides 6 and 7 for empty cans and guides 8 and 9 for filled cans. Empty pots 10, pots 11 filled with a tape machine (under the paver), filled pots 12, moving along the fixed base 13, and the axis 14 of the inner guide 9 also participate in the process. The latter is connected by an extension spring 15 with a fixed base 13 .

The drive 1 reciprocating movement of the rod 2 with the pusher 3 and the rotational movement of the rod 4 with the grip 5 is fixedly mounted relative to the listed elements and is kinematically connected to the rod 2 and the terminal 4. It is placed in the rod 2, aligned with it with the possibility of rotational movements relative to It is caused by the drive 1. The pusher rod 2 is made in the form of two symmetrically fixed at the end of the rod 2 rods 3. The rods 3 are attached to the rod 2 on both sides at an acute angle to it. The gripper 5 is made in the form of two straight plates rigidly fixed at the end of the string 4 and symmetrically with respect to the rod 4 at a right angle to it. The guides 6 and 7 for empty pelvis are parallel to each other and the rod 2 on both sides symmetrically with respect to the axis of the rod 2 and fixedly mounted with the ability to interact with the empty basins 10. The guides 8 and 9 for filled basins are made symmetrically with respect to the rod 2 under

acute angle to it from two sides. Outer guides 8 and inner guides 9 are mutually parallel to each other at each release. External

guides 8 are fixedly mounted with the possibility of interaction with the filled basins 12. The inner guides 9 are mounted with the possibility of interaction with the empty

basins 10 filled with basins 11 and filled with basins 12, as well as with the possibility of angular displacements relative to the fixed base 13 on the axis 14. This guide 9

mounted on a fixed axis 14 pivotally with the possibility of rotation relative to it.

The lower end (relative to the axis 14) of the guide 9 is connected to the spring 15

stretched on a fixed rack and holding the guide 9 in a vertical position in the absence of pressure from the empty pelvis 10.

The pusher 3 and the guides of the filled cans are placed in such a way that the apex of the angle formed by the rods 3 is opposite to the apex of the angle formed by the guides 8 and 9.

The proposed device operates as follows.

The actuator 1 moves the rod 2, the pusher 3, tgu 4 with the grip 5, relative to the guides 6 and 7 and 8 and 9 in the direction of the empty cans 10 to the position of the gripper 5 behind the first pair of empty cans. In this case, the gripper is in position 1 (Fig. 7).

With this movement, the pusher 2 presses

on pots 11, which were under operating time, moving them along guides 8 and 9 into the zone, accumulated basins 12 relative to the stationary cicHOB 13. After pushing out the filled basins 12, the actuator 1 turns the pu 4 with the gripper 5 by 90 to position II (Fig 7), and then moves the rod 2 with the pusher 3, the tug 4 with the grip 5 and a pair of basins 10 to its original position, setting the basins 11 to be filled with tape, when the empty basins 10 move along the fixed guide 13 into the stacking area

tapes. The pots 10 are pressed against the inner rail 9, turning it 90 relative to the fixed axis 14, and the spring 15 is extended (Fig. 3.4).

In the horizontal position, the guide 9 does not interfere with the movement of the pelvis 10, and after passing it, the spring 15 returns the guide 9 to a vertical position. Spring 15 prevents movement of guide 9 in the opposite direction. Therefore, when the pusher 3 pushes 11 are pushed out, the guide 9 prevents the latter from entering the area of the cans 10 and promotes the displacement of the cans 11 into the area of the filled cans 12.

In the proposed device, the work cycle consists of four movements: two translational and two rotational, there are no idle strokes. Moreover, the rotational movement makes only the grip 5 with the thrust 4, which constitute only a part of the mass of the mechanism for pushing out the cans.

The proposed device in comparison with the known one allows a 1.8-fold decrease in energy consumption due to the complete elimination of idle strokes and unnecessary work sub-cycles within the cycle. Moving to empty basins 10, the pusher pushes the developed basins 11 into the area of filled basins 12 along the guides 8 and 9. Moving in the opposite direction, the gripper 5 moves the empty basins 10 under operating time. The rotational movements at the same time make only the capture of 5 with th 4, the mass of which is 1.6 times less,

than in the known device. The number of drive transitions: start-stop is reduced 1.5 times.

The proposed device also allows a 1.4-1.6 fold reduction in the area occupied by the machine with the same number of basins in the known device. This effect is achieved by reducing the width of the machine. In the case when the rod 3 pusher

mounted at an angle of 45 to it, and guides 8 and 9 for filled cans are located at the same angle, the width of the machine is reduced by 1.4 times; in the case when the rods

set at an angle of 60, and guides 8 and 9 at an angle of 30 °, the width of the machine is reduced by 1.6 paiaa (Fig. 5, 6).

In addition, 1.4 times easier.

organization of the pusher and grip movements, since the translational and return movement of the rod takes place at the same distance, and the rotational movement of the grip -

constant angle, and in the proposed automaton of movements 1.5 times less.
